LAMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 577,943, dated March 2,1897. Application filed May 19, 1896. Serial No. 592,144. (No model.)

To aZZ whom it may concern.-

Be it known that I, MARY W. BEATON, a citizen of the United States, residing at Bellows Falls, in the county of Windham and State of Vermont, have invented a new and useful Lamp Attachment, of which the following is a specification.

This invention relates to lamps; and the object in view is to provide an attachment for a lamp by means of which the rays of light may be focused or condensed, thereby intensifying the light and projecting its rays to a greater distance than ordinarily. The attachment referred to may be constructed either as a part of the lamp or it may be made a separable part thereof, so that it may be readily attached and removed when desired.

To the above end the invention consists in certain novel features and details of construction and arrangement of parts, as'hereinafter fully described, illustrated in the drawings, and finally pointed out in the claims hereto appended.

In the accompanying drawings, Figure 1 is a perspective view of a lamp with the improved attachment shown applied thereto, the lamp-shade being partly broken away to show the manner of supporting its frame. Fig. 2 is a plan view of the band of the attachment.

Similar numerals of reference designate corresponding parts in both figures of the drawings.

Referring to the accompanying drawings, 1 designates a lamp of any ordinary construction having the usual fount or oil-reservoir 2, of circular or cylindrical form. The attachment contemplated in this invention consists of an annular band 3, of any suitable material, such as sheet metal, having its opposite edges rolled or otherwise reinforced, as indiare also extended tangentially to the band 3, thereby locating said sockets at points remote from the outer surface of the band. The band is also provided upon one or both sides with longitudinal slits adjacent to its beaded edges,

and the material included between said slits is deflected inward, as shown at 6, thus forming a yielding portion by which the band is adapted to clasp the lamp-fount with the necessary pressure to hold the same in place, the said band being introduced over the upper portion of the fount, as shown in Fig. 2.

7 designates a pair of spherical globes,which are transparent and which are provided with pendent stems 3, adapted to enter the sockets 5 of the band, whereby they are held in place at either side of the lamp. These globes are also provided at their tops with tubular necks 9, by which they are adapted to be filled with water or other liquid, suitable stoppers being thereafter introduced into the necks for preventing the escape of the liquid. These globes being located at each side of the burner of the lamp, as shown in Fig. 1, they act as lenses or magnifying-glasses and take up the rays of light and project them in opposite directions and serve to greatly intensify the light and cause the same to penetrate to a'greater distance.

The lamp-shade 10 is mounted upon a suitable frame ll, having oppositely-extending arms 12, extending toward the globes 7, and is provided with rings or loops 13, which are placed over the tubular necks 9 of the globes, thus holding the shade in place.

The attachment above described may be made in various sizes to suit different lamps and may be made either separately from the lamp, so that it may be applied to lamps already in use, or it may form a part of the lamp.

Of course where the improvement constitutes a part .of the lamp the major portion of the band 3 may be dispensed with, it being necessary only to employ the sockets in which the globes are placed.

It will be apparent that the attachment adds greatly to the usefulness of the lamp in that it materially increases the light, enabling the finest print to be read at a considerable distance therefrom.

Changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, What is claimed as new is-- 1. A lamp provided at each side with opposing sockets, in combination with the transparent globes containing liquid seated in said sockets and located upon opposite sides of the burner, the projecting necks at the tops of said globes, and the lamp-shade having the rings or loops for engaging said necks, substantially as described.

2. The combination with a burner, of upper and lower frames having oppositely-disposed sockets approximately in vertical relation, and a lens having oppositely-disposed necks to enter the said sockets, substantially as and for the purpose set forth.

3. In combination, a burner, upper and neck on said globe, and a lamp-shade having 0 a loop for embracing said neck, whereby said shade is supported, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

MARY W. BEATON.
